FAQs About Butterfly Valves

Most frequent questions and answers

1. What is a butterfly valve used for?

Butterfly valves are used to regulate or isolate flow in pipelines. They are commonly found in water distribution, wastewater treatment, stormwater systems, and industrial applications due to their reliable shut-off and compact design.

2. How does a butterfly valve work?

A butterfly valve uses a rotating disc mounted on a rod to open or close the flow of liquid. When the disc is turned parallel to the flow, the valve is open. When it is rotated perpendicular, the valve is closed, allowing for quick operation and minimal pressure loss.

3. What are the advantages of butterfly valves?

Butterfly valves are lightweight, cost-effective, and easy to install. They provide reliable sealing, require less maintenance than other valve types, and can handle large volumes of fluid with minimal space requirements.

4. Are butterfly valves suitable for wastewater applications?

Yes. Butterfly valves, especially those built with corrosion-resistant materials like AVTEK valves, are ideal for wastewater systems because they withstand harsh environments, chemical exposure, and abrasive conditions.

5. What sizes are butterfly valves available in?

Butterfly valves come in a wide range of sizes, typically from 2 inches up to 72 inches or more. The correct size depends on your pipeline diameter and flow requirements.

6. What types of butterfly valves are there?

The most common types include concentric (resilient-seated), double-offset, and triple-offset butterfly valves. Each is designed for different levels of performance, temperature tolerance, and sealing capability.

7. How do I choose the right butterfly valve for my system?

Choosing the right butterfly valve depends on your application, fluid type, pressure rating, and environmental conditions. At DL VEWS, we work with engineers and contractors to recommend the best AVTEK butterfly valve for your specific project.

8. What materials are butterfly valves made from?

Butterfly valves can be manufactured from materials such as ductile iron, stainless steel, PVC, and epoxy-coated steel. AVTEK butterfly valves use high-performance, corrosion-resistant materials to ensure long-term durability in harsh water and wastewater environments.

9. Can butterfly valves handle high pressure?

Yes, but the capability depends on the valve design. Standard concentric butterfly valves are suitable for low to medium pressure, while double-offset and triple-offset butterfly valves are designed to handle higher pressures and temperatures.

10. How long do butterfly valves last?

With proper selection, installation, and maintenance, butterfly valves can last 20 years or more. AVTEK butterfly valves are engineered for extended service life, helping municipalities and industries reduce replacement costs over time.
